DEVICE FOR CONTROLLING FLOW OF WATER IN PIPES.

SPECIFICATION forming part of Letters Patent No. 673,165, dated .April30, 1901. Application filed November 16, 1900. Serial No. 36,753. KNOmOdeL) To all whom t may concern:

Be it known that I, PAUL P. I. FYFE, a citizen of the United States, anda resident of Concord, in the county of Cabarrus and State of NorthCarolina, have invented a new and Improved Device for Controlling theFlow of Water in Pipes, of which the following is a full, clear, andexact description.

One purpose of the invention is to provide such a connection between thewater-supply and water-service pipes that the water may quickly iiowfrom one to the other or whereby the connection between the pipes may becut off any length of time, during which time all the house-pipes Willbe empty of water and the water thus freed conducted to the sewer orother drain.

A further purpose of the invention is to accomplish the above-namedresults through the medium of a single slide-valve operated within thebuilding.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawing, forming a part ofthis specification, in which is represented a vertical section through apart of the lower portion of a building and adjacent ground and apartial side elevation and partial sectional view of the improveddevice.

A represents the cellar or lower portion of a building; B, thewater-main; C, the sewer or other drain; D, the water-supply pipeconnected with the main and which extends within the apartment A, and Ea portion of the service-pipe forthe building. These two pipes D and Eare connected by a valve-casing F, and in this valve-casing a plug 10has sliding movement, the plug being provided with an opening 11,extending through from side to side and which in one position of theplug connects with both the water-supply pipe D and the service-pipe E.The valve-plug 10 is further provided with an angular opening or port12, and this angular port or opening extends through one side only ofthe plugthat side which faces the service-pipe E-and the verticalportion of the angular opening or port 12 extends out through the bottomof the said plug.

A hub 13 is attached to the bottom portion of'the casing, both the topand bottom of the casing being open where the plug 10 has movemeut, andthis hub 13 may constitute a portion of a drain-pipe 14, and such pipeis usually carried to the sewer C or other convenient conduit.

The plug 10 is shown operated through the medium of a lever 15, which isfulcrumed upon a suitable support 16, located within the lower apartmentA of the building, and one end of this lever 15 has a link and pivotalconnection 17 with the upper portion of the valve-plug 10, while aspring 18 may be attached to the opposite end of the said lever 15 andto any support. This spring 18 may be so arranged that it will normallyhold either one of the two ports in the valve-plug in position forservice; but the spring 18 may be omitted and the lever 15 may beoperated by hand.

In operation when water is to be supplied from the main B to theservice-pipe E the valve-plug 10 is lowered and the upper or throughport 11 is placed in communication with the pipe leading from the mainto the near-by service-pipe. Should it be thought that the Water in theservice-pipe might freeze during the cold weather, the water may betemporarily shut off from the main B by car-A rying the through-port 11to the upper por tion of the valve-casing and bringing the angular port12 in communication with the service-pipe connected with the valvecasing, whereupon water will be cut off from the supply-pipe to thevalve and its casing; but all the water contained in the house-pipeswillescape through the angular outlet-port 12 and through the medium of thebranch drain-pipe 14 to the sewer.

Having thus described my invention, I claim as new and desire to secureby Letters Patent-- 1. In a device for controlling the flow of water inpipes,\a supply-pipe, a service-pipe, a

valve-casing connecting the two pipes, a plug mounted to slide in saidvalve-casing and provided with a port extending through from side IOO toside and adapted to register with both the supply and service pipes, anda second port Aextending through one side of the plug onl)T ing acentral opening extending through from top to bottom, and which is incommunication with both of said pipes, of a plug held to slide in thesaid central opening of the valve-casing, the plug extending through andbeyond the valve-@asin g at the top and at the bottom, the said plugbeing provided with a throughport extending from one side to the otherand adapted to register with both of the said pipes, and asecond angularport which extends from one side and out through the bottom of the plug,the angular port being adapted for registry withrthe service-pipe only,an offtake, a connection between the lower portion of said valve-casingand said otake, a lever, and a link connection between said lever andthe said valve-plug,for the purpose described.

3. The combination with a Water-supply pipe, and the service-pipe, of avalve-casing connecting the two, a plug mounted to slide in said casingand provided with a port adapted to register with both the supply andservice pipes, and a second port adapted to connect the service-pipewith an offtake leading from thevalve-casing, a lever fulcrumed on asuitable support, a connection between one end of the said lever and thevalve-plug, and a spring connected with the other end of said lever andwith a support, for the purpose set forth.

In testimony whereof I have signed my naine to this specification in thepresence of two subscribing witnesses.
